HPFE Gen-2 HPFE is a dedicated flash architecture with all-Custom Flash Hardware (CFH), which is... [More]

True flash architecture – that means being designed for the purpose of ultra-high performance from scratch, and not being limited by a Device Adapter, or FC-AL shortcomings. If you look at the specs of typical SSDs of today, each single drive could do tens of thousands of IOps, but when it comes to creating a RAID across a small pack of these, then we see the real results. Traditional architectures often also call themselves “flash”, but in fact were just using SSDs and kept putting them behind the same Device Adapters that... [More]
